Hi Dean; Big welcome to Permies! We like it when lurkers step out in front of the curtain!
I know absolutely nothing about growing
mushrooms, other than attempting to grow psyliciban mushrooms under my bed in the 1970's (Big failure).
I do know a fair bit about
Rocket mass heater's though. So stop on by the
rmh forum and we will share that info.
As far as your question of how to post about your experiments.
If you have
enough info to make a
thread about each experiment, then I would post individually. This leaves room for others to comment on each experiment in full
